A guide to select your perfect laptop

1. SizeThe size of a laptop is definitely one of the first things you'll need to look at when buying a laptop. There are a number of different sizes of laptops that are available on the market ranging from 10.5" to 17". Laptops can range from the bulky MSI GL72M to the thin LG Gram. The size of the laptop obviously affects its portability and also dictates the size of the keyboard and the touchpad. 2. ThicknessThinner laptops are usually lighter and easier to carry (not to mention the fact that they look really nice) one of the prime examples being the MacBook Air. But the downside is that they generally have lesser ports and are equipped with a smaller battery, which can be a deal breaker if you are planning on connecting a number of devices to the laptop. Thinner laptops are also usually more expensive as well. 3. Display sizeAs mentioned earlier, the size of the display will affect a laptop's portability.

How to make the hard disk not recoverable while selling it using ubuntu

You need to securely destroy your data while selling it or handing over to another person, because the data can be recovered from the hard disk even if you format it many times. There are many software tools which can do this, but this is the simplest way i found and the safest.

The safest way is to overwrite the whole hard disk with random data. This way your private files are not recoverable after this.

You can use an Ubuntu live usb to perform this if you are selling your computer.
Just boot up from the live usb to ubuntu or any other linux to perform this. you dont have to install any additional tools to do this, you can use the built-in 'dd' command which is available in any linux distro.

the command format is:

#sudo dd if=/dev/urandom of=/dev/sda bs = 4096 status=progress


This command will destroy the whole data including the partition and file system in /dev/sda. So please make sure /dev/sda is the drive which you want to erase before doing this.
